Mary Gay Potter Haldeman has a Master's degree in Spanish Literature from the University of Maryland and another in Linguistics, from the University of Iowa. She teaches in the Writing Center at Massachusetts Institute of Technology (MIT) every fall, specializing in English as a second language.

The rest of the year she resides in Florida, where she manages writer Joe Haldeman's career, dealing with editors, answering correspondence (in Spanish and French as well as English; isn't e-mail wonderful?), serving as travel agent, answering the phone, typing and filing, arranging publicity, selling Joe's out-of-print books, etc. She's been going to SF conventions since 1963 (so has Joe) and loves to meet new people. After 42 years of marriage, she still thinks Joe's the best thing that ever happened to her.
